octave-interval FTBFS against octave 6.
The issue has been forwarded upstream:
https://savannah.gnu.org/bugs/index.php?59617
Also, there is bug report on the upstream BTS regarding the failure of
the unit tests against Octave 6:
https://savannah.gnu.org/bugs/?func=detailitem&item_id=59334
I narrowed down the problem to the following example:
This works with Octave 5:
$ octave-cli --version | head -n 1
GNU Octave, version 5.2.0
$ echo 'pkg load interval; fsolve (@sin, infsup (-1, 1))' | octave-cli -q
ans = [-0.0078125, +0.0078125]
but it fails with Octave 6:
$ octave-cli --version | head -n 1
GNU Octave, version 6.1.0
$ echo 'pkg load interval; fsolve (@sin, infsup (-1, 1))' | octave-cli -q
error: Invalid call to fsolve. Correct usage is:
-- fsolve (FCN, X0)
-- fsolve (FCN, X0, OPTIONS)
-- [X, FVAL, INFO, OUTPUT, FJAC] = fsolve (...)
[…]
Is this a problem in Octave 6 (overloaded function not being recognized)
or a problem in the interval package?
